目前许多公司都有来自多家供应商的存储系统,这些系统部需要包括在同一个存储区域网络(SAN)之内,而且必须通过一个单一界面和管理模式来对它们加以管理那么如何才能管理异构存储环境?答案就是SAN存储虚拟化技术。康柏公司对认为存储虚拟化是对存储器的抽象,它通过运用块级映射技术,以虚拟磁盘的形式为主机服务器提供了一个存储器逻辑视图,同时它也使存储数据块到物理存储设备的工作以一种对服务器完全透明的方式进行。这一抽象使得许多重要的新性能得以实现,从而简化了在OpenSAN(开放式存储区域网络)环境下对存储器的管理和配置工作。
Many companies today have storage systems from multiple vendors that need to be part of a single SAN and have to manage them through a single interface and management model The storage environment? The answer is SAN storage virtualization. Compaq believes that storage virtualization is a memory abstraction that provides a logical view of the host server in the form of virtual disks by using block-level mapping techniques, and it also enables the work of storing data blocks to physical storage devices In a way that is completely transparent to the server. This abstraction enables many important new features to be realized, simplifying the management and configuration of storage in OpenSAN (Open Storage Area Network) environments.
